Snakes of Wisconsin

Snakes play very important roles in many natural communities as predator and prey. They are extremely valuable to the agricultural community by keeping grain eating mammals in check. Recent studies suggest that snakes are also valuable in reducing disease threats posed by high rodent populations. Many snake populations have declined in Wisconsin due to habitat loss and human persecution. Even today, people who do not understand or appreciate their value continue to needlessly kill them. Of Wisconsin's 22 species, 14 are considered "rare" and listed as endangered, threatened or special concern.
